The "zcviewingkey" field has never been documented before, and the method itself
is deprecated; this just ensures it is consistent with the rest of the RPC.
The wallet code previously assumed that an unlocked wallet would always
have a spending key associated with a note decryptor. Viewing keys break
this assumption.
Track net value entering and exiting the Sprout circuit
Delta values will be stored for new blocks; old blocks can be filled in by
re-indexing. The net value currently in the Sprout circuit is only calculated
when delta values for all previous blocks are present.
Part of #2351.
Block indices are flushed to disk when they are marked as dirty, and this
happens via enough distinct pathways that it would be sufficiently complex to
update nSproutValue via all of them. Thus it is necessary to be able to
serialize "no value" for writes by upgraded clients.
Fix buffer overflow in libsnark
Applies `-fstack-protector-all` to libsnark, and fixes an underlying bug. This bug was not triggerable in `zcashd` because the function in question was being inlined by the compiler.
Closes#2788.

Add examples for z_rpc calls
Adds missing cli and json-rpc examples for `z_` rpc calls
Closes#2723
(Accidentally named the branch being merged in with wrong issue number)
noexcept is default for destructors as of c++11. By throwing in reverselock's
destructor if it's lock has been tampered with, the likely result is
std::terminate being called. Indeed that happened before this change.
Once reverselock has taken another lock (its ctor didn't throw), it makes no
sense to try to grab or lock the parent lock. That is be broken/undefined
behavior depending on the parent lock's implementation, but it shouldn't cause
the reverselock to fail to re-lock when destroyed.
To avoid those problems, simply swap the parent lock's contents with a dummy
for the duration of the lock. That will ensure that any undefined behavior is
caught at the call-site rather than the reverse lock's destruction.
Barring a failed mutex unlock which would be indicative of a larger problem,
the destructor should now never throw.
Get rid of underscore prefixes for include guards.
This is because they may conflict with reserved names. Also took
this opportunity to make the guards in the zcash subdir a bit
more uniform by having them all conform to ZC_<...>_H_
This closes#1272
Remove Boost conditional compilation.
Boost is currently at version 106200 in the depends subsystem
so it is safe to remove code the refers to earlier versions.
This closes#2445

Previously libsnark would try to build libgtest if /usr/src/gtest
exists on the build machine. This caused issues because the
version of libgtest in /usr/src isn't necessarily the same as
the one that the rest of zcash's gtests were built with.
